Objectives It is unclear what is driving rising colorectal cancer (CRC) treatment costs in China, whether an adjustment in drug prices changes use and total cost. This study aims to estimate trends in drug use, prescribing patterns and spending for antineoplastic drug therapies for CRC in major cities of China.Methods Information from 128 811 antineoplastic drug prescriptions in CRC was retrospectively collected from the Hospital Prescription Analysis Cooperative Project. The prescriptions extracted included demographic information of patients, the generic name and the price of antineoplastic drugs. The Mann-Kendall and Cochran-Armitage trend test was used to estimate the trends of antineoplastic agent usage.Results The number of antineoplastic prescriptions ranged from 18 966 in 2015 to 34 219 in 2019. Among the prescriptions collected in this study, the annual cost of antineoplastic drugs increased by 117.2%, and average prescription cost increased by 20%. Throughout the study period, the most prescribed antineoplastic drugs were capecitabine, oxaliplatin, fluorouracil and irinotecan, representing 49%, 27%, 21% and 9% of (per cent of visits (PV)). The PV of bevacizumab and cetuximab increased by 494% and 338% (from 1.8% and 1.3% in 2015 to 10.7% and 5.7% in 2019). In prescribing patterns of antineoplastic agents, monotherapy gradually decreased, while combination therapy, especially three-drug combination, increased significantly from 1.35% to 7.31%.Conclusion This study estimated recent trends of antineoplastic drug use and expenditure for Chinese patients with CRC. These results would inform CRC treatment decisions, including health insurance negotiation, precision therapy access, allocation of research funding and evaluation of the financial burden of CRC drug treatment.
